Yes Max you are correct. I install again I tried BUT and MB Recaster, both times the result is the same.
I am missing something, because with IceCast the player display the name of the song, with Steamcast does not.

You will need to modify your scripts to pull their stats from either /status.json or /status.xml select the appropriate file for your parsing needs Steamcast supports both JSON and XML processing.

The structure of the JSON or XML file will absolutely different from what Icecast2 sends so you will need to make modifications to your scripts to find the right target. If you want us to do this work for you we can quote you a price for our time to make the changes.

Alterantively we have an example PHP script that works perfectly with Steamcast.
